Answer:
The correct order is (b), (a), (d), (c).
Explanation:
Given:
Correct order is as follows,
(b) White light with all colors is emitted by the sun.
(a) White light interacts with molecules in the atmosphere.
(d) When interacting with molecules, blue light with shorter wavelength scatters more in all direction.
(c) Light that is primarily blue comes from all directions in the sky.
Therefore, the correct order is (b), (a), (d), (c).
Answer:6.36 ft
Explanation:
Given
there is 110 ft of deer-resistant
area enclosed must be at least 700 ft^2
Let the length be L
and area of rectangular garden is 110\times L
thus
L=6.36
Therefore Length of garden must be at least 6.36 ft
Answer:
Explanation:
Let the amplitude of individual wave be I and resultant amplitude be 1.703 I . Let the phase difference be Ф in terms of degree
From the formula of resultant vector
(1.703I)² = I² + I² + 2 I² cosФ
2.9 I² = 2I² + 2 I² cosФ
.9I² = 2 I² cosФ
cosФ = .9 / 2
= .45
Ф = 63.25 .
A) 1 rev = 2π rad. Using this ratio, you can find the rad/s: 1160 rev/min x 2π rad/rev x 1 min/60 s = 121.5 rad/s
b) You can find linear speed from angular speed using this equation (note the radius is half the diameter given in the question): v = ωr = 121.5 rad/s x 1.175 m = 142.8 m/s
c) You can find centripetal acceleration using this equation: a = v^2/r = (142.8 m/s)^2 / 1.175 m = 17 355 m/s^2
